LAN'DI-GRADER. 1

Patented Aug. 4:, 1914.

Application filed. May 14, 1913. Serial No. 767,570.

To all whom it may concern:

Be it known that I,MANUEL P. MONTE, a citizen of the United States, residing at Stockton, in the county of San Joaquim State of California, have invented certain new and useful Improvements in Land- Graders; and I do declare the following to be aclear. full, and exact description of the same, suchas will enable others skilled in the art to which it appertains to make a j and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon,

which form a part of this application.

This invention relates to improvements in devices for grading land, the object of the invention being to produce such a deviceas may be positioned at one point and then operated to thoroughly level and grade a predetermined piece of land in a rapid and eifective manner. 1

A further object of the invention is to produce a grader which will, when once p0- sitioned, automatically grade and level the land until it is perfectly level, all of which can be done without the necessity of using leveling instruments of any kind.

Another object of the invention is to produce a power operated grader which will, when positioned, move backward and for ward automatically until the ground over which it is working is perfectly level and which is then capable of being moved along a short ways and the leveling operation repeated and so on until a large predetermined strip of land is leveled.

A still further object of the invention is to produce a device which has various adjustments whereby the same is hired at a level and also whereby the same can be eX- tended 0r shortened accordingly as a larger or smaller strip of land is to'be leveled.

A further object of the invention is to produce a simple-and inexpensive device and yet one which will be exceedingly effective forthe purposes-for which it is designed.

These objects, 'I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of thefollowing specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the several views.

Figure 1 isatop plan view of the complete device, as it appears when in operation. Fig. 2 is a side elevation of the grader. Fig.3 is an end view of the completedevice. Fig. 4 is a top plan view=of a fragmentary portion of the device showing the gradingplows and barrows and the adjusting means therefor. Fig. 5 is a sectional view taken one line X-Xof Fig. 4 showing the adjusting means for the plows and harrows of the device.

Referring now more particularly to the characters a of reference on the drawings, the numeral 1 designates the main frame of the device which consists of two or more members suitably hinged as at 2 and provided with a central slot 3 on each side of which slot the said member 1 is provided with tracks or runnersl. At each end of the member 1 is a bolt 5 adapted to project through a slot 6 in a vertical beam 7 having at its lower ends a pair of spaced branches 8, each branch carrying in its lower end a turnable wheel 9 on which wheels the entire device is supported.

Secured on eachend of the member 1 is a yoke 10 having freely turnably mounted therein a threaded pin 11, which pins project in a threaded manner through projecting flanges 12 on the upper end of each of the members 7 said. pins 11 being provided with operating wheels 13 on their up per ends. By means of the structure just described the frame 1 may be adjusted to a level position irrespective of the positions of the members 7 by loosening the bolts 5 and operating the wheels 13to adjust the member-1 on the members 7 to a level position. This level position can be determined by placing a level on the member 1 or by having a level glass carried continuously by said member 1. Then when this member 1 is set at a level position, the bolts 5 may be again tightened and the grading plows and harrows are then suspended on the members 1 and moved backwardly and forwardly on the same by means of the followingstructure, to-witw: Mounted on the member 1 on each side of the slot 3 are the rails 4 over which operate wheeled trucks 15 carrying a platform 16 'on which is mounted the seat 17 for the operator. Movable vertically through the platform 16 and projecting disposed on the lower end of said beam 18 swingingly mounted onwhich pin is a projecting arm 27. The plow structure then consists of two guides 28 secured to the lower end of which is a curving member 29 and on each end of each curving member is a grading plow or scraper 30. Connected to the end of each member 28 and extending to the rear of each plow or scraper 30 is a narrow or scarifying member 31. An arm'82projects from each of the members 28 above the members 31 and are connected to said members 31 by brace members 33. On the outer end of'each arm 32 is another projecting arm 34 carrying .in its outer end a pulley 35. Secured to the member 18 above the pin 26 is a cross arm 35 having a roller 36 in each end.- On one of the members 7 there is a drum 37 and onthe other there is a drum 38. Secured to the drum 38 are two cables 39 and 40. The'cable39 projects under one i of the rollers 35' overthe corresponding roller 36 and is then connected back between the corresponding arms 34and 32 as at 41. The other cable 40 'proj ects across and around the drum 37 and then under the other roller 35 over the corresponding roller 36 and is similarly connected between the corresponding arms 34 and 32 as at 42.

With the operation of the drum 38'which is vdriven by suitable gearing 43 operated by a tractor 44, one or the other of the cables 39 or 40 is operated accordingto the direction in, which :the drum 38 is operating. This then "first swings the scraping mechanism on its pivotal point 26 until one of the members 28 engages the beam 18 which stops the pivotal movement and then the continua tion of the pulling on the cable drags the beam 18 and all its connected parts along the track members 4 which causes that scraper 30 which is in engagement with the ground to scrape the ground for the full length of the device, the harrowing'me'ans 31 loosening the ground behind the scraper sothat when the device is reversed "the ground will be loosened and'moreeasily scraped. Then when thescraping mechanism reaches one end or the other of'the device the engine is reversed and the other cable'is wound up on the drum 38 which reverses the position of the scraper mechanism and then reverses its movement as will ap- 25, projecting through the slot 3, to

pear and by this means thesame 'may be swung backwardly and forwardly until the ground underneath the memberl is graded to the same level as the said member 1 and since the member 1 can be set level by the adjustment means this assures of the ground to a perfect level.

As has been noted the member 1 is formed in two parts hinged together-as at 2 and suitably braced by supportingtrunnions 45 having a center turnbuckle adjustment 46 in order to hold the same perfectly level and rigid/ 'VVhen however the device is to be transported, the brace may be removed and one of the bolts 5 loosened and the members 1 on one side of the hinge 2 turned backwardly toproject along the sides of the other ones, the members 7 having been previously operated forward and connected to the stationary half by means of projecting the bolt through holesfft i When one'stretchof land is to be graded, posts 47 may be positioned at proper points the grading and providedwith pulleys 48 over which i may extendcables 49 adapted to be operated bya drum 50 on the tractor 44 whereby first one stretch of land is graded under neath the device which may be advanced then to another position until a'large surface a has been suitably graded, all of which will be perfectly level as can be seen since the device when once set level cannot do otherwise than level the land" beneath'it.

My device may be found especially adaptable for grading land. for irrigation purposes but also can be used in any capacity where grading land is required such as the filling in of low places, ditches or 'intfact'any class of grading'workl ,From the foregoing description it will readily be seen that I have produced such a the objects 'of device. as substantially fulfils the invention as set forth herein; 1

While this specification sets forth in dei. i

tail the present and preferred construction of the device, still in practice, suchdeviations, from such detail may be resortedtto as do not form a departure fromthe spirit of the invention. i I
